This is how I am gonna get Tubi content…

• open stream in browser
• hit F12 to get tools and click Network tab
• filter for m3u8
• copy the URL to the clipboard
• timeout -s 2 90m yt-dlp -o "tubisave.ts" "URL"

The "-s 2" sends SIGINT to the downloader after 90 minutes and the .ts file is the content.
